Why is a high amount of genetic variation within a species good?

Variation is caused by a mutation to the base sequence of DNA. It can be good if it helps with survival. It is also to do with natural selection. For example, plants with bigger leaves can take in more sunlight and can make food easily.
So if some plants with a range of different leaf sizes e.g 2cm-8cm, are living near the bottom of a forest and then some other plant comes along and grows to be taller than the first plants and blocks off sunlight, the original plants with smaller leaves die off. They can't get enough sunlight to make food. Now there are bigger leaved plants growing near the bottom and when they reproduce the pass on their good, big leaved genes. So now there are more big leaved plants in the population.

How can genes be altered and combined to create genetic variation within a species?
Through different types of mutations.ChromosomalinsertiondeletiontranslocationinversionGenesubstitutioninsertiondeletion
How does natural selection produce genetic variation within a species?
It's mainly mutations in the DNA and recombination of chromosomes that produce the genetic variation. Natural selection then favors those changes that give rise to greater reproductive success.
What is the major cause of variation within species?
sexual reproduction is the major cause of variations within a specie
What process during meiosis leads to genetic variation?
DNA organizes into chromosomes within the nucleus
What is the difference between anatomical anomaly and biological variation?
Biological variation is much wider term. It takes place at the level of species while anatomical anomaly means a anatomicaly different individual within species.
Is adaptations a genetic basis for variation within a species?
No, adaptations usually do not result in any genotypical change in a species.
How do the Grants data show that genetic variation is important in the survival of a species?
The Grants' work shows that variation within a species increases the likelihood of the species' adapting to and surviving environmental change.
How does variation within a species bring about evolutionary change need specific example that also mentions genetic variation and environmental conditions?
yes

Why genetic variation is of to benefit to a population?
It can provide resistance to diseases or other beneficial characteristics. -variation in more competitive species than our own can result in natural selection that is better focused to the specific environment: there is a bigger range of characteristics, so the best traits allow those members to survive longer and therefore mate more. This allows the species overall to constantly reproduce the beneficial traits and flourish.
What id genetic variation?
Genetic Variation is a measure of the genetic differences there are within populations or species. For example, a population with many different alleles at a locus may be said to have a lot of genetic variation at that locus. Genetic variation is essential for natural selection to operate since natural selection can only increase or decrease frequency of alleles already in the population
What causes variation within species?
Variation within species can be caused by genetic mutations, environmental factors, and interactions between genes and the environment. Genetic mutations are changes in the DNA sequence that can create new traits. Environmental factors, such as diet and climate, can also influence variation by selecting for certain traits over others.
How does natural selection produce genetic variation within a species?
It's mainly mutations in the DNA and recombination of chromosomes that produce the genetic variation. Natural selection then favors those changes that give rise to greater reproductive success.
What are specific examples of variation within a species?
Human species, as in the variation in height.
What is the major cause of variation within species?
sexual reproduction is the major cause of variations within a specie
How do genes control variation within a species?
Genes control variation within a species through the expression of different traits. Variations in genes lead to differences in physical characteristics and behaviors among individuals. This genetic diversity within a population is important for adaptation to changing environments and for the evolution of species.
What is a major cause of variation within species?
Variation of a species can come about in many ways, but mutation is the major cause of variation in a species.
